Private schools achieve that and have more ability to do so than homeschooling teacher as a service does.

This model isn't new and had problems before.

If I can find a news article about a public school teacher who molested children will you support shutting those down too?

I think your article is less likely to have the investigation beginning with the post office and more likely to have affects of multiple regular people not being OK with something, and being present.

Such involved parents could never let anything happen arguments ignore how these things develop as less involved parents cargo cult. (You can't get much more blatant in a drop in actual involvement than the example.)

These kinds of groups connecting themselves to actual home schooling will erode it by association.

If I can find an article about a parent molesting a child, will you support sending them to public school?
